Mercury amalgam concentration

The most commonly used method for reducing an aryl ketone to an alkylbenzene employs a zinc-mercury amalgam m concentrated hydrochloric acid and is called the Clemmensen reduction Zinc is the reducing agent... [Pg.486]

Chlorine—hydrogen ha2ards associated with mercury cells result from mercury pump failures heavy-metal impurities, particularly those with very low hydrogen overvoltage, ie. Mo, Cr, W, Ni excessively low pH of feed brine low NaCl concentrations in feed brine and poor decomposer operation, which leads to high sodium amalgam concentrations in the cell. [Pg.82]

Clemmensen reduction The reduction of a carbonyl group using a zinc/mercury amalgam and concentrated HC1 to give the methylene unit. [Pg.357]

The mercury vapor produced by bubbling the sulfur dioxide through a mercurous nitrate solution was detected by the gold-coated crystal due to the formation of a mercury amalgam. The optimum conditions were temperature = 27°C flow rate = 55 ml/min [Hg2 ] = 4 x 10 M purge time = 10 min. The sensitivity of the detector depended on the sample size, and linear calibration curves in the concentration... [Pg.292]
